Doing some computer archaeology, I have a soon to be vacant InWin A500 casing, it's at the moment housing a malfunctioning Pentium II, the casing is ATX, I have a caseless 386 machine which will fit the ATX casing, I've done it before, I have a ATX Aopen HX-45 which is the home of a original IBM AT.
So the ATX powerbutton can be replaced by an AT switch, the InWIn A500 casing is so old that they prepared the mounting holes etc for it, so the only little thing to fix is to decide what powersuply I can use...
I have 3 AT powersuplies, one is my regular fan, CD-ROM, HDD etc tester, it works, even the fan is in good shape, so that's the easy one.. powersuply Nr2 is a Taiwanese built "Treetop" 200 watt standard Pentium era PSU, it has no fan though, it is a well built PSU, did surprise me, all caps are high quality ones, problem is that I can't see where the fan is usually connected to, I did see a connector of somekind though so that might be it.
The last one is also a Taiwanese PSU, a Jabert 200 watt PSU, opened it up, it's well built and has Rubycon capacitors, even the bulk caps are made by Rubycon, having that brand of caps usually means that the PSU is made to a high standard.
It did have a weird problem, the AT switch is a real physical switch it's not connected to a mainboard but to the powersuply, it is a real powerswitch, it has 4 wires connected to it, black, blue, white and brown, on the PSU there's a schematic printed, it was wired wrong, that's ultra weird..
I got the two powersuplies as a gift from a colleague about 20 years ago, I have never used either of them, I have reconnected the switch according to the schematic so cross fingers, I'll try both of them when I have the time this week..
